7 Grid Connection in Japan Wind power was not allowed to use grid connection between each area. Wind potential exists strongly in Hokkaido, Tohoku and Kyushu. 7

8 However, we have delay of more than 10 years for offshore in Europe. Furthermore, the national project is planned to have only one turbine. We should accelerate wind power to cover nuclear in high speed. 8

16 METI Offshore Wind Energy Project, Fukushima (FY2011~15) Floating offshore wind farm demonstration project (FY rd supplementary budget : 12.5 billion yen) Contents of project Summary / Purpose Affected areas in the east, in particular, Fukushima, are recovering from the earthquake damage. These areas are expected to provide large scale job creation due to accumulation of industries focused on renewable energy. Image of project Demonstration area : offshore of Fukushima Prefecture Such areas as well as a better wind conditions, are expected to take advantage of the former facilities of the offshore gas field, already being developed or currently in not use, offshore areas of Fukushima Prefecture are favorable. This project will clarify the safety, reliability and economic potential of floating offshore wind by demonstration and experiments of the world's largest level floating offshore wind power generation system off the coast of Fukushima prefecture. After the completion of this project, This project is sought to make a new power generation business through the development of equipment as a result of this project. By doing so, we aim to make a Japan a hub of wind power and contribute to the industrial revival in Fukushima 地上高 70mの年平均風速 (m/s) Demonstration assumed area Conditions(applicant, subsidiary rate, etc.) Entrust METI Source : METI, Japan Private Organization, etc Image of floating offshore wind power (provision:mes, Tokyo Univ., TEPCO) 16

27 Concluding Remarks Roadmap is discussed for wind power with estimation of potential for wind power. FIT is expected to work well to develop wind power. Primary grid connection of wind power is important with the electric power company using the connections with other areas. Offshore wind power has large potential due to the huge area of ocean around Japanese island of EEZ 6 th. Deep offshore system will be a key technology for future development of wind power and recovery from the disaster. Fisherman s right will be reasonably taken into account for cooperating with developer instead of compensation. 27
